[QUOTE="RocketCowboy, post: 670437, member: 25095"] The Core Duo processor is pretty old ... I'm thinking 2007ish?? As I recall, it's a 32-bit processor, so it's not able to recognize more than the 4GB of RAM currently installed. I still have my first MacBook pro ... with a Core 2 Duo processor, and it only recognizes 3GB of the 4GB of RAM installed. So that said ... yes, Lightroom would LOVE for you to have more memory installed. I would suggest 8GB as a minimum, and as Marcel said, 12GB or more would be ideal. I run 16GB of RAM on my laptops, and 32GB of RAM on my desktop ... but I don't notice a significant speed improvement with Lightroom on the desktop, so 12-16GB is probably the sweet spot. Lightroom also can take advantage of the GPU on your graphics card, so an iMac refresh would help there. I don't think you'll see much improvement for your email and remote desktop use, but photo editing will for sure.
